However...................and I think that I posted this before. Although I think that it would be more difficult to get in on another car's pass on Friday, when it is quite quiet, I reckon that on the other two days it could be possible.
Saturday and Sunday mornings, around 9-9:30am at the exhibitors' gate can get pretty busy. Cars are streaming in by the dozens. They are directed by the marshals through only one entrance gate with half a dozen scrutineers checking tickets and passes. They then allow you in and thence over the the bridge at Bridge.
Now, having had passes for a few years now, if I were to try to get in with another car's infield pass - which of course I certainly would not do - I'd conveniently 'forget' to stick the pass on my car's windscreen and when challenged I would whip it out and wave it about waftily, at the same time apologising for being such a dozy get and promising to stick it in the correct place once I've gotten to the Maserati stand.
Not that I'm suggesting that this strategy would work, mind you.
And at least I may be able to see what I'm signing..!!
